Pull request overview

• The PR title/description says CI should use the stable ESLint v10, but the matrix include entries for Windows/macOS still install eslint@latest. This can pull ESLint v11+ once released and makes CI no longer consistently exercise v10 across OSes. Consider switching those eslint: "latest" entries to 10.x (or another explicit v10 range/pin) to match the PR intent.

                eslint: [9.15.0, 9.x, 10.x]
                node: [25.x, 24.x, 22.x, 20.x, "20.19.0"]
                include:
                    - os: windows-latest
                      eslint: "latest"
